The Gym Is A Man's World

The gender that diets most shows up less frequently at the gym. A University of Michigan study published in the American Journal of Public Health found that young women in their 20s consistently exercised less than their male counterparts. The research analyzed data over a 23-year period and included 17,314 males and females aged 19 to 26.

The Bigger Picture: In addition to questions about exercise, subjects were asked how much sleep they got, how long they watched TV, if they regularly ate breakfast, and how many of their meals included fruits and vegetables. The goal was to pinpoint energy gaps. That's when an individual takes in 100 or more calories per day over and above what they expend. How does your lifestyle compare?
